Some one wants me to run a cable for them. It is to be run from the cable TV connection on the house to an out building in the back yard. The distance is roughly 220 ft. What type/size cable would anyone recommend I use?

The only problem with this is that I would have to join a bunch of pieces.
I have to find it in bulk,maybe a 250 ft roll.

I believe Lowes and Home Depot both have it on a spool and cut what ever lenght you need. Then just add your ends. But add ends carefully. I have seen Sat and Cable installers put the ends on incorrectly and I ended up redoing them when people would call and complain about there poor picture.

Connectors actually make a very big difference. I ran RG6Q distribution in my house, and was careful to use crimp style RG6Q connectors. My signal strength was low. The cable guy came out and measured the signal strength and confirmed that it was very low. He changed out the connectors at the pole and at my terminus block and the signal improved. He was nice enough to change out my crimp connections for his long sleeve commercial press on style, and the signal strength went up again. While I rarely have much to thank Comcast for, I can say that the technician was very helpful that day.

Crimps are fine IF done correctly. I use weather proof crimps inside as well as out and never had a problem.

Certainly - anything done correctly works fine. I did not want to imply otherwise. I thought I was being careful when installing the crimp style connectors, but apparently I did not do such a good job. I have since changed to the push on style and seem to be able to install them consistently. Maybe I wasn't holding my mouth right when I was doing the crimps, or the planets were not in alignment, or maybe I just wasn't paying attention that day.

Non spliced RG11, then get it tested for signal strength .

I was only referencing that product as an example of the cable type that I meant. As others have pointed out, you can usually buy any cable in bulk off of a spool.
So will it be buried or aerial?

RG11 could also be used and is suppose to have less signal loss on longer runs, however this is only when comparing the same manufacture of the 2 cables. It is possible the get a higher quality RG6 that will have less signal loss then a lower quality RG11 so its still a crap shoot which is better unless you have access to both types in higher quality. Plus RG6 is more commonly found in retail market. The difference between the 2 of equal quality would be 100 feet of RG6 would have the same signal loss of 130 feet of RG11. Again the ends have a more critical issue of signal quality if not installed properly. If RG11 is available to you in a good quality then why not use it. I think it's still priced about the same.

I have found a lot of RG-213/U showing up in the surplus market. Is it a good choice?

It will run under the house and then be buried in the yard.

RG-213 is no good for cable or sat. Is has a 50 ohm rating where as RG6 and 11 are 75 ohm which is required for devices in cable and sat signal viewing.
RG-213 is for VHF signals such as short wave and ham radio antenna's , radar devices and VHF radios and so on.
